I specified this AuthQueryViewer definition
Title = “MQ Events”,
DefaultSearchText = “MQ”,
DefaultSearchField = “What”,
DefaultSearchType = “=”,
DefaultFields = “Id,UserAccountId,Time,What,Src,Dest,RestCall,Url:30,JsonLen,MsgDescribe:5000”
The Search field is populated, the SearchType is populated but the SearchText is not populated on the screen.
